The Applications of Phoenix Contact PSR-SCP-42-230UC/URM4/4NO/2NC

1. Robotic Welding Cell Safety Expansion

In robotic welding stations, operators must be protected from entering active zones while machines are running. Light curtains or safety doors provide the signal, but additional controlled outputs are often required. The PSR-SCP-42-230UC/URM4 module extends available contacts, allowing several contactors, alarms, or drives to be shut down at once. With force-guided relays and wide voltage compatibility, it ensures dependable redundancy and makes the safety system robust against component failures.

2. Furnace Motor and Fan Shutdown

In high-temperature furnace operations, coordinated shutdown of motors and ventilation fans is essential during service or emergency stops. The URM4 module enables multiple circuits to be controlled from a single safety event, ensuring every component switches off simultaneously. Its furnace-ready approval and stable performance across wide voltage ranges make it particularly suited for heat-intensive industrial environments, helping avoid damage and enhancing operator safety.

3. Packaging Line Gate Interlocks

Large packaging lines feature several safety gates and emergency buttons across different stations. A single safety relay may not provide enough outputs for all actuators and indicators. By integrating the URM4 extension module, the system gains extra reliable outputs while maintaining top-level safety standards. Operators benefit from simple fault diagnosis with clear LED indicators, while the plant ensures that every safety gate properly interrupts hazardous energy sources across the entire line.

4. Hydraulic Press Dual-Channel Control

Hydraulic stamping presses demand strict redundancy to prevent unintentional movements. Two independent monitoring channels are used, but additional outputs are often required to disable clamps, relays, and alarms. The URM4 extension module provides the extra switching capacity while ensuring both channels are correctly followed. Its force-guided contacts confirm switching accuracy, while fast response times help prevent unsafe restarts. This results in a safer, more reliable press control system that fully complies with international safety requirements.
